Answer:
And the best option would be:
0.094 to 0.146
Step-by-step explanation:
For this case we have the following info given:
represent the proportion estimated
represent the standard error
represent the confidence level
The confidence interval for the true proportion is given by:
And for 95% of confidence the critical value is 
and replacing we got:
And the best option would be:
0.094 to 0.146
If the metal strip goes around the bench, then we are looking for the perimeter.
P = 2L + 2W
P = 2(9) + 2(4)
P = 18 + 8
P = 26 feet
Then, we know that the stripping costs $5 per foot, and we need 26 feet of the stripping.
26 x 5 = 130
Total cost = $130
Hope this helps!
I'm not sure but I think it is the first one
Answer:
(0, -6/5)
(-3, 0)
Step-by-step explanation:
y-intercept is when x is 0.
x-intercept is when y is 0.
Answer:
150°
Step-by-step explanation:
to find the individual angle of a REGULAR dodecagon (which means that all sides are equal), you'd use the equation I(individual angle)= (n-2)×180/n
N is number of sides. The number of sides on a dodecagon is 12. So, substitute N for 12
I= (12-2)×180/12 which simplifies to 10×180/12
10×180= 1800
1800/12 = 150
so, an individual interior angle of a dodecagon is 150°
